弹性件设置在点式盘式制动器的轭架和扭矩吸收结构之间，弹性件在致动状态下仅在间接致动的摩擦垫磨损到轭架朝向制动盘的表面移动超过预定距离的程度时才对轭架起作用，从而使制动踏板的行程突然变大，从而向驾驶员发出摩擦垫磨损到危险程度的危险警告。
Elastic members are disposed between yoke and the torque absorbing structure of a spot-type disc brake, the elastic members reacting against the yoke under actuated conditions only when an indirectly actuated friction pad is worn to such an extent that the yoke travels towards the face of a brake disc in excess of preselected distance, thereby to abruptly make the stroke of a brake pedal large so as to give a warning of danger to a driver that the friction pad is worn to a dangerous extent.
